portupgrade: odd behaviour with -p

[Angelo Turetta]

Since the recent upgrades (in the last couple of months, I'd say) when I 
run some variant of:

     portupgrade -aRp

I noticed that, in case some port fails during build or install, the -p 
option will repackage the existing port. You can verify it by simply 
pressing ^C during compile phase.

I don't think this is the intended behaviour.
